Ignition Interlock Device Laws in Arizona

ignition interlock device laws

An ignition interlock device (IID) tests the alcohol levels of drivers before allowing them to start their vehicle. For those who have previous convictions of a DUI on their record, this is how the state ensures that you don’t become a repeat offender.

After serving the license suspension sentence for your DUI conviction, the courts will require documentation proving that you have installed an ignition interlock device. Depending on the terms and conditions your Arizona DUI attorney was able to negotiate for your case, you might have limited driving privileges even during court proceedings. During this limited license suspension, you could be required to use an ignition interlock device.

An Arizona DUI conviction carries with it a mandatory year of using an ignition interlock device. The law is outlined in Arizona Revised Statute 28-1464.

How does an ignition interlock device work?

The way the device works is that it measures blood alcohol content through a breath test. If the test detects any level of alcohol at all, it will not allow the driver to start the vehicle. Some devices are also sophisticated enough to require random tests throughout longer travel to allow you to continue driving.

Current technology does not measure drug use, but researchers are working to resolve that. If your charges are for using drugs and driving impaired, you will not be required to use an IID since it does not measure drug use.

Arizona DUI law concerning tampering with an IID

When serving an Arizona DUI sentence that includes using an IID, it’s extremely important that you follow the rules that the courts outline. Failing to do so could mean extended sentences, jail time or new convictions.

If you’re caught tampering with an IID, the courts will not look kindly on you. Tampering with an IID might mean using a vehicle that is not equipped with the device, such as a borrowed or rented vehicle, or having someone else breathe into the device for you.

Tampering with an IID is a violation of your probation, which means that the courts could automatically suspend your license, send you to jail or increase the severity of your DUI sentencing.

There is only one exception to these rules around an IID and that’s if there is a serious emergency where you must drive a vehicle without the IID installed. In cases of emergencies, you can drive another vehicle, assuming of course that you are not intoxicated and putting other drivers at risk.

Where can I get an IID and how much does it cost?

Arizona has vendors that sell and install an ignition interlock device in accordance with court requirements. Installation generally starts at $70, with $150 being the most expensive installation fee. Your vehicle and the complexity of the install will dictate how much the company charges you for installing the ignition interlock device.

Additionally, you’ll need to pay a monthly rental fee for the device itself. This can cost $40-$120 depending on the model your car requires. You can find state-approved IID installers on the Arizona Motor Vehicle Division website. Using an approved vendor means that you’ll get all the necessary proof and paperwork to give to the courts to prove you are in compliance with your sentencing.

Hiring an Arizona DUI attorney is your best chance at avoiding conviction or getting the most favorable sentencing terms for your case. Failure to present a case in court can mean that you receive the highest conviction and penalties the law allows.

There are a variety of ways an attorney can defend your case and work to either prove your innocence or lessen your conviction. Hire a good attorney to avoid serious consequences following an Arizona DUI charge.
